Canadian Governor General decides to be -- Canadian.

This story is self-explanatory (reproduced in entirety in case you are not registered at the Toronto Star.)

Michaëlle Jean is giving up her dual French citizenship as she prepares to take up her post as Governor General of Canada.
In a brief statement issued Sunday, Jean said she was making the move given the duties she will be assuming, including the title of commander in chief of the Canadian Forces.

She said French authorities have acceded to her request to renounce her citizenship in that country.

The Haitian-born Jean, who grew up in Montreal, acquired French citizenship when she married film-maker Jean-Daniel Lafond, who was born in France. Jean will be installed Tuesday as Governor General, succeeding Adrienne Clarkson.
